Oh no not another free will thread.

[Edwardo Piet]

Relating this idea to the whole box universe thing.  If we are a series of states all occurring at the same time, if someone were able to access states at later times, they would be able to see results.  You add another point outside of the box, and get a perspective from there, you could see all of the states simultaneously.  None of this knowledge would provide a cause for an acausal event.

I'm talking about causes beyond our experience, you're still talking about our experience. As all knowledge is inside our experience.

This is what this quote is getting at:

We know nothing about the intrinsic quality of physical events except when these are mental events that we directly experience.

^I need to put this in my signature. It's an awesome quote.
